—We consider power control in spectrum overlay networks (also referred to as opportunistic spectrum access) where secondary users identify and exploit instantaneous and local spe...
In this paper, we present a graph-theoretic framework for provisioning overlay network based multimedia distribution services to a diverse set of receivers. Considering resource l...
In this paper, we present the design of foundation PKI (fPKI), a PKI system constructed on an overlay network for an open source community. fPKI can provide an alternative PKI sys...
P2P systems are increasingly used to discover and share various data between users. The performance of a P2P based information retrieval system is determined by the efficiency of...
This paper describes and evaluates Fireflies, a scalable protocol for supporting intrusion-tolerant network overlays.1 While such a protocol cannot distinguish Byzantine nodes fro...
